Neuropathy and leg cramps

I have burning and tingling in my feet which has gotten steadily worse over the years. I mostly notice it at night after getting into bed. Some nights they are on fire, other nights it's not too bad. I have never been to a neurologist. But I also suffer, and I mean suffer, from nocturnal leg cramps. The PN website notes muscle cramps/twitching as a symptom of neuropathy. Does anyone else experience leg cramps along with the neuropathy? I am desperate for a solution as I have tried many things. Magnesium at bedtime; epsom salt soak; magnesium oil with massage; stretching; exercising/not exercising; nervive; capsacin creams. Nothing always works, so I don't know what actually can work; perhaps I haven't found the right combination?
I do take 30mg of amitriptyline every night for the neuropathy. Perhaps I need to check with my DCP about upping the dose?
Thank you for any help you can give!
